Subject: [PATCH] build(gateway): skip fixupPhase to kill 'patchelf: wrong ELF
 type' noise
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

dontPatchELF only disabled the patchELF sub-phase; fixupPhase's
shrinkELF step still emits the same error on the prebuilt .node addons
and .o/.a object files in node_modules. Skip the entire fixupPhase
(dontFixup = true) for the gateway — node is the external interpreter
and .node addons are self-contained dlopen prebuilts, so Nix RPATH
patching/stripping is neither needed nor wanted.
